<p class="MsoPlainText"><o:p> </o:p></p>

<p class="MsoPlainText">Two different cases of the same symptom have been identified (so far). When building $TAO_ROOT/orbsvcs/FT_Naming_Service, I get undefined symbols while linking:<o:p></o:p></p>
<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText">CosLoadBalancing::AMI_StrategyHandler::__descr .obj/FT_Naming_Main.o (symbol belongs to implicit dependency $ACE_ROOT/lib/libTAO_CosLoadBalancing.so.2.3.0)<o:p></o:p></p>

<p class="MsoPlainText"><o:p> </o:p></p>
<p class="MsoPlainText"> SAMPLE FIX/WORKAROUND:<o:p></o:p></p>
<p class="MsoNormal">For FT_Naming_Service, the problem is resolved by addling libTAO_CosLoadBalancing.so to the link line. Unfortunately, I couldn’t figure out how to modify the MPC files to accomplish this, so my local workaround modifies the GNUMakefile.FT_Naming_Service
directly<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For Random, it was a little more puzzling, since the problem exists in a local file. However, grep shows that RND_Timer is not actually used; simply removing the class definition from Random.h works.<o:p></o:p></p>
